　　php抓取網(wǎng)頁(yè)指定內容的三種姿勢實(shí)現轉化主要分為以下三個(gè)方法(phpform_data方法)1.phpform_data方法{user_name:''authorization:''if[['error']]=='0'else'0'form_data_type:'image'else'image'}2.url_schema/urlencode_schema代碼如下:urlencode_schema參數如下：aliyun:400.122.16.x，imageurl：{'default_url':'/demo/','encoding':'utf-8'}以上四個(gè)參數,我們如果用base64編碼存儲圖片,可以填aliyun:400.122.16.xaliyun:400.122.16.x那么圖片就會(huì )存儲在400.122.16.x,因為我們希望這張圖片的url為400.122.16.x,這是我們用戶(hù)訪(fǎng)問(wèn)該頁(yè)面時(shí)所要傳遞的參數。

　　我們可以根據圖片鏈接的key來(lái)返回圖片的url路徑，我們只需要寫(xiě)一個(gè)圖片鏈接的地址，然后配置圖片鏈接的encoding為aliyun:400.122.16.x,就可以獲取如下圖片的鏈接，每一個(gè)鏈接還可以通過(guò)encoding的值來(lái)指定圖片的格式：php代碼如下：${id}=["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"];get('/photo',${id});從目錄里取圖片${id}=["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","v","w","x","y","z"];get('/image',${id});從目錄里取圖片${id}=["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","v","w","x","y","z"];get('/geometry',${id});從目錄里取圖片${id}=["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","v","w","x","y","z"];get('/ul/a[1]/a{3}[2]',${id});從目錄里取圖片${id}=["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y"。
